lVlETHOD F APPLYING AN ADVERTISING AND gRgSER-RETAINING FERRULE TO A PENCIL H FT Robert E. Yaw, Cedar Rapids, Iowa Application June 25, 1952, Serial No. 295,424

1 Claim. (Cl. 15483) This invention relates to pencils of the type having an eraser that is secured on the body of the pencil by means of a metal ferrule. Pencils of this character provide inexpensive and highly attractive advertising media particularly if the metal ferrules are attractively lithographed or printed; but in order to provide for practical lithography or printing in colors on the ferrules, the lithographing or printing must be applied to the ferrules in fiat or sheet form, after which the individual ferrules are cut apart and brought to cylindrical form with opposite edges in substantial abutment. This construction leaves an open searn extending longitudinally of the ferrule and unless such ferrules are made of relatively thick gauge material and/or have a high degree of elasticity, the ferrules will not stay on the body of the pencil and the erasers cannot be retained therein without the use of a cement material.

Heretofore when cements are used, they have resulted in an unsatisfactory product because the ferrules expand suificiently to allow the cement to exude through the seam of the ferrule. Therefore, the pencils must be cleaned to remove the exuded material.

It is, therefore, the principal object of the present invention to provide an advertising or souvenir pencil having a construction which is particularly adapted to lithographed ferrules and which provides for secure retention of the eraser on the body of the pencil and without causing exuding of the cement material through the scam.

in accomplishing this and other objects of .the invention hereinafter pointed out, I have provided improved structure, the preferred form of which is illustrated in the accompanying drawing wherein:

Fig. 1 is a perspective view of a pencil constructed in accordance with the present invention.

Fig. 2 is an enlarged perspective view showing a strip or sheet which has been lithographed or otherwise printed in fiat condition to provide the blanks from which the ferrules are formed.

Fig. 3 is an enlarged perspective view of one of the formed ferrules and the end of a pencil to which it is adapted to be secured.

Fig. 4 is a similar view after the ferrule has been applied to the body of the pencil and a quantity of cement material placed in the ferrule ready to be flowed into 7 spaces that are provided between the ferrule and the body of the pencil.

Fig. 5 is a perspective section illustrating the pencil after the eraser has been applied and the cement material squeezed into the spaces that have been provided to receive it and thereby prevent the surplus material from exuding through the joint of the ferrule.

Referring more in detail to the drawings: i

1 designates a pencil constructed in accordance with the present invention and which includes an elongated body portion 2 and which may be of circular cross section and includes a wood casing 3 for a coaxial pencil lead 4. Fixed to one end of the body of the pencil by means of a ferrule 5 is an eraser 6. The eraser 6 has a cylindrical periphery 7 and substantially flat end faces 8 and 9.

In carrying out the present invention, the ferrule 5 is formed of light gauge sheet material such as a metal and is li-thographed or printed as shown in Fig. 2 on one of the fiat surfaces 10. The lithographing or printing maybe provided in a plurality of colors in that the strip or sheet material may be run through conventional color or lithograph press, or the colors may be applied by other methods while the strip is in flat condition.

After the colors have been applied, the ferrules are cut from the strip or sheet material to provide substantially individual squares having side edges 11 and 12 and top and bottom edges 13 and 14, the squares being of suitable dimension so that when they are rolled in cylindrical form, with the edges 11 and 12 in substantial abutment as shown in Fig. 3, the exterior diameter thereof will substantially correspond with the exterior diameter of the body of the pencil. The squares are rolled into cylindrical form with the printed and colored surface outermost in accordance with the present invention. The inner face 15 is of slightly larger circumference than the periphery of the eraser 6 to accommodate therebetween a film 16 of the cement material by which the eraser is secured in the ferrule as later described.

In order that the ferrule may be securely applied to the body of the pencil, the end 17 thereof is of reduced diameter to form an annular shoulder 18 encircling a reduced terminal 19 that is of a diameter to fit freely within the ferrule and leave an annular space 20 therebetween into which the cement material is caused to flow as later described.

To better provide for easy flow of the cement material and assure against exuding thereof through the abutting ends of the ferrule, the terminal 19 is preferably in the form of a frustrum of a cone so that the entrance 21 to the annular space 20 is of greater width immediately surrounding the end face 22 of the pencil body as shown in Fig. 4.

In assembling the parts, the ferrule as shown in Fig. 3 is sleeved over the terminal 17 so that the edge 14 seats on the shoulder 18 and the outer end forms a socket 24 to contain the eraser. A measured amount of cement material 23 is then applied in the socket 24 through the open end of the ferrule as shown in Fig. 4, the quantity of material being only suflicient to form film 16 and substan-tial-ly fill the annular space 20 when the eraser 6 is pushed into the open end of the ferrule. When the eraser is moved into place, the end 9 thereof cooperates with the end face 22 of the terminal 17 of the pencil to cause the cement material to move downwardly into the tapering annular space 20 and upwardly within the space 16 as shown in Fig. 5, with the eraser being inserted into the ferrule for a predetermined distance so as to leave a portion 25 of the cement material between the end face 22 of the terminal 17 and the end face 9 of the eraser as shown in Fig. 5.

It is obvious that the annular space which is provided for receiving the measured amount of cement material eliminates building up of any pressure that might cause the ferrule to expand and cause extruding or exuding of the cement through the seam of the ferrule. Therefore, the printed and decorated surface of the ferrule cannot be smudged or smeared with the cement material.

It is also obvious that after the cement material is set, the ferrule is securely retained on the body of the pencil and the eraser is securely retained in the fer-rifle.

What I claim and desire to secure by Letters Patent is:

A method of making and applying an advertising ferrule for retaining an eraser on the shaft of a pencil including, applying an advertising material to the ferrule While the ferrule is in flat condition, rolling the ferrule into cylindrical form to bring opposite edges thereof into abutting contact, removing an annular portion of the shaft to form diameter af'sa'id shoulder smaller than the inner diameter of the ferrule and providing a continuous annular space therebetween increasing incapacity toward the outer end of the ferrule when the ferrule is piaced over the terminal', placing a quantity of cement material within the ferruie in an amount sufficient to fill said annular space and additionally to occupy an annular space between the eraser and a portion of the ferrule projecting above said terminal and to leave some cement material between the end of said terminal and the end of the eraser, pressing into the ferrule anteraser of such smaller diameter than the inside diameter of the projecting portion of the ferrule as to force the cement material downwardly from the larger toward the smaller end of said annular space and,

upwardlyiinto the space between the. projecting end of the ferruleand the eraser without causing exuding of the cement material through the seam formed by said abutting 4'. ends of the ferrule-forretaining the eraser in the ferrule and said ferrule on the shaft solely by means of the cement material.
